Your BMW's timing belt is responsible for timing the valve train to the crankshaft. Timing belts can stretch out and fray due to constant heating a cooling cycles as well as constant tension. We recommend replacing this belt along with the tensioner every 4 years or 50,000 miles for the best service life and performance. This is important because the M20 engine is an interference engine. Failure of this belt will likely destroy the cylinder head and cause severe damage to the engine.
